Depends on your users I think. If 50% of that traffic is during a 10 hour window of time each day, that could be around 70 views per second. And pulling email for an account could be more costly than a static page view. Then if he's getting that many views, he could be processing tens or hundreds of emails a day per account more or less.... Could get expensive.

How do you get that? Assuming 4M/month, that works out to 130K/day. Even if all that traffic comes in a 10-hour window, that works out to 130,000/36000 =~ 4/sec, not 70/sec.
